Mmm/E555@ abkomwq lll said gear 2l' heilig; adapted to engage or mesh with a similar beveled eer 28 which ie keyed to the transverse sheA t 19. By rotation of the crank 2G, the carriage block 1S is moved accordingly.. A. transverse shaft 29 is mounted 'Within the eerrioge hlorl i8 :it one end, end is jooruelled. to the bracket 2l by .means of a. journal 3l et opposite end, and is adapted to carry a beveled BO. A loiigitodinsil shell; 32 is so mounted, es to carry e. beveled geef to mesh with. the geer, so that the rotation of the creol: 33 will similarly rote'fe 'the shaft't. A pinion is carried on the opposite end oi' the transverse shaft 29 end is positioned 'Within o recess .in She carriage bloc-lr 18.

The numeral 36 designates any type of plow or ehi other earth Working element, hot e dou le beam plow is preferable. The earth Workin element 36 is provided with sod Cutters l which will out; the sod so that they will be easier to handle, and which will adept; them to be more easily used, when discharged from my machine.

.The of the earth Working element 36 is provided with e depth googze 38,. seid depth gauge being regulated hy a. pivoted rook lier 39", pivoted to the loeom oy means of a bolt or the like 4G', Said rair'lc hor meshing with the pinions on the shall' if), .lt will thus he seen that. the rot-ation oi' the sho ft- 29 will reise or lower (he rock liar 39 which will io. adinet the depth fiorito 38. rlhe eer Worh'iiil @temeon 3o r I ilaecl by ole 3S* is oomieffted one end to' the boem by means of :z cho 110. The cable 39 pr .s over :i pulley ll `which is mounted upon the carriage hloel( lll, ood is connected et its opposite ood to o. drum 5&2, Solid drum heilig mounted on :l eli t el which is journallocl oy f. jooinal 4 to ,the transverse he drum is operated by moons f. l thus be seen that by roh ingr the emol( the drum will lilco'iifse he rotated. and il fehle 39 will he wound or mwoorid therefrom, f ependingz open lhe direction in Whrh theemnk 45 is moved, und the earth working element 36 will be raised or loo-ered accordingly.

The numeral fl designates the Side beam ot' the lower Conveyor or elovetoi'.y "whirh le designated in. its entirety lijf lhe immoral l2". The earth Workin;w element, 36 is Connected to the side beams 46 by momie of o. hrocket:

which is universally joined :il Lvif). to allow for the varrone zuljustmeiie. Monoted between the Sido lienzos LLG ot' the com veyor are rollers Themmierall represents :i comme or 'tho-.Ilka endless hoh: having theusuol slots 5:2. The drivngroller is mount l :it the opper end of the two beams 46, Suid driving roller being provided with e sprocket The numeral 55 deeigrnotes gear Wheel which is carried by the righi; hand Wheel `18 and is roeeted therewith. A Uoheped frame member o6 1S so situe-ted as to encircle the right, hand gear wheel 13 and is connected to the right; hand longitudinal beam l() by means of holte Mounted oo the U-slieped from@ ,5o is o Small shaft 5S which ,is 'journallccl to the from@ 56 hy means of e journal (lo ooo eocl of the shaft 5S is n pinion 60 which is eclepted to 'mesh with the larger gear wheel 35, and the other end of the shaft 58 heilig provided with o. sproeket (il. chain ie adapted to coimecl' the Spfoelret Wheels 54 ...nfl (il.

le will. thus he s eii that when the'vehiele or road grader is moved the large gear Wheel will rotate, thereby rotating the pinion (l0 which in turn will rotate the shalt oorrying the Sprocket 5l, thereby imparting movement to 'the sprocket chain 62 which will rotae the Sprocket wheel 5e, which will likewise rotate the drinn 53 Wl'iich will more the endless Carrier or belt 47.

The numeral G23 represents the upper oonveyox.' in ite entirety. The conveyor provided of -h two eide beams (Sil, which o." spaced eport hf; :Beams or' (he rollers 55, over 'which canvas bell: 6o rims1 seid eeuws boltlieing pr aided with the hemel slots til.

A sp1-ovl rhein Si) connects the sprocket when; GS) :mil TS). ll' will thus he seen that hy moulin-ent o the road grader, the large goor wheel T() will rotate thereby rotating the smaller pinion 7l which in toro `will rotate the shaft (2 which will rotore the beveled goor 74. The beveled 'geur To meehiog' with goor Zd 'will lio caused to rotate :uid will likewise rotate the shall; 7G Corrying the sprocket- Whcel 79, thm-ehu' rf. ting the Sprocket rhein S() which will ro: te the sprocket wheel (Si) rotating the emllees lit-lt (3G.

Mounted on the umher Side of the upper conveyor, is :i mechanism which ie adopted to separate the cloth; :ind top lsoilA from the under soil und clay. The nonierel resents o depending V-slmpe l hrziel-rf is seurvfl to the under eide ol the conveyor benin (i22- by menne of bolts 3 course similar depending Vlehm al l are provided on both ot the bee" defleetor plete 82 is pivoted between die Vehoped brackets 83, and is edapied to be swung in the various positions as is shown in Figure 3 oi' the drawings, in full lines and dotied linee. i link Sl is pivoted to the detleeor plate 5&2 at 85, and is ,adapted to lie edjustahly secured to ne lower arin o'l the lil-shaped brackets 8l, by reason of the apertures 86 and tlie pin 87. lt will 'be seen that when the dirt strikes the delector plaie whenit is in the position es is indicated by the letter A in Figure 3, the dirt will fall in tlie direction o the. arrows D, into 'the Center of the road. However, when the de'tleclor plate is tilted in the position as is indicated by the letter B, lie dirt will nethrown to one side o the road as is e early illusiialed h3," the arrow E. lilien 'ilie deilector plaire is situated in the position indicated in lieary lines ily the letter C, 'the dirtJ will fai-.l iii e vertical position.

Mounted near the lower end ol" tlie upper conveyor 63 is a bracket nieinlier S3 Wliioli is adapted to receive a vertically extending pin 89. Mounted on the Lipper end of the lower conveyor, is a bracketV 9U Wliieli is adapted to reeeire a. soclzc'u ineinlier 9i, said socliet member being adapted to receive the pin member 89 forming a connection, or support between elle two conveyors. This road grader is guided hy means of :i steering wheel 02 having a drnni 9B which cari-ies a cable Se to the 'liront wheels. The drirers seat is designated hy the numeral 95, and it will be seen that all ol the ogei'ziting nicchanisin is readily acerssilile 'li-oni this sexie,

The operation oi r-lie device is es follows: The earth w rking element 36 is set to `ny depth desired off ineens oli the c anke 33 and 4F. The dirt is carried lroin the earth Working element, onthe conveyor i7 to the conveyor 6T, which conveyor provided with a dellector plate 82 which determines in which direetien the diffJ or sod, as the ease may loe, shall oe thi-own. if 'this inecliine is used on new ground, the deflector plate will lie sei in tlie position es is illustrated by the letter l5 in liligure 3 el the drawings, ther-elija' causing; the sod to be thrown' to one side. Aitor the sod lies been removed, the deiieetor plete may be set, es is designated by the letters A or C, and the earth ivill he allowed to Jfell vertiieellv or deliected inwardl1 toward the center oi the rond. This deflector plate `vill :iid consider ably in forming' the necessary crest that, is desired for the purpose of drainage, in the making of :i new road. t- Will further aid -iii cutting' fio-celled ridges and filling; up ihn to Jfoi-in. a level road. Furthermore it is oi'tcn times inconvonient to run a rood grader too near to the edge ol the road, and to tolte care of this liollows so as @,t'i diflciilty, l here provided ineens ii'lierelij; ilie earth working eleiiifiil muy lie adjusted 8l oy ineens of the pinsv ioward or away ioiii the ironie o the road grader, so that the road grader inail i'iin on eoiiiriaratii'ely level ground while the earth working .leiiientl is vcutting a like. a is lo he liirtlier noted that the power required to operai-e the endless conveyors is derived lire-cialii iron?. *die more` nienty oi' the veliirle, iii suoli a manner, that it will readily ne seen that, the road grader isincreased the speed or the conveyors Will. likewise increase. t is to be noted tliiil. any form of power inegi lie used izo repel this road grader, bill, ie gireferred tiet this road ri-ader lie pulled inv stead oi. pushed.

it is to be understood that the forni oi' my invention herewith shown and described is io lie taken as preferred einloodiiiien el the seine, and that; rarioiis changes in the shape, size and arrangement ofi parte may lio resorted to, without departing li-oni the spirii, of iny ii'irention or the scope o" 1the sulii oined clziinis.
